TECHNICAL FIELD

Embodiments of the disclosure relate to the field of communication, andmore particularly to a method and device for transmitting an uplinksignal.

BACKGROUND

In the present Long Term Evolution (LTE) communication system, asingle-carrier transmission manner is adopted for uplink transmission,and uplink transmission is implemented mainly through a Discrete FourierTransform-Spreading-Frequency Division Multiple Access (DFT-S-FDMA)waveform. A main characteristic of the single-carrier transmissionmanner is that a Peak to Average Power Ratio (PAPR) is relatively low.That is, during uplink signal transmission between a terminal and anetwork device, the terminal may use relatively high power withoutworrying about that peak power may exceed the maximum transmitting powersupported by the terminal. In the single-carrier uplink transmissionmanner, the transmitting power of the terminal may be convenientlyimproved to improve transmission quality of uplink transmission andextend coverage of the uplink transmission.

However, when the single-carrier transmission manner is adopted totransmit an uplink signal, physical resources for transmitting uplinkdata are required to be continuous in frequency domain to meetcharacteristics of the single-carrier transmission manner From theabove, when physical resource configuration manner for single-carriertransmission is adopted for transmitting uplink signals, uplink signalsof only one type may be transmitted on a whole allocatedfrequency-domain physical resource in a time-domain scheduling unit (forexample, a slot), so that flexibility of uplink signal transmission islimited.

Alternatively, the wireless communication system 100 may further includeother network entities such as a network controller and a mobilitymanagement entity. There are no limits made thereto in the embodimentsof the application.

It is to be understood that the technical solutions of the embodimentsof the disclosure may serve various communication systems, for example,a Global System of Mobile Communication (GSM), a Code Division MultipleAccess (CDMA) system, a Wideband Code Division Multiple Access (WCDMA)system, a General Packet Radio Service (GPRS), an LTE system, anAdvanced Long Term Evolution (LTE-A) system, a Universal MobileTelecommunication System (UMTS), New Radio Access Technology (NR) and5th-Generation (5G).

It is also to be understood that, in the embodiments of the disclosure,a terminal device may include, but not limited to, a Mobile Station(MS), a mobile terminal, a mobile telephone, UE, a handset, portableequipment and the like. The terminal device may communicate with one ormore core networks through a Radio Access Network (RAN). For example,the terminal device may be a mobile phone (or called a “cell” phone), acomputer with a wireless communication function and the like. Theterminal device may also be a portable, pocket, handheld,computer-embedded or vehicle-mounted mobile device.

In the embodiments of the disclosure, a network device may be an accessnetwork device and, for example, may be a base station, a Transmit andReceive Point (TRP) or an access point.

There are no specific limitsmade thereto in the embodiments of the disclosure.

Multiple services exist in a future 5G communication system, forexample, Enhanced Mobile Broadband (eMBB) and Ultra Reliable Low Latency(URLLC). Different services have different uplink signal transmissionrequirements. For example, some services require a terminal to feed backwhether downlink data transmitted by a network device is successfullyreceived or not relatively fast to reduce an overall transmission delayof the downlink data. Some services require high-capacity feedback to besupported during uplink signal transmission. For example, uplink signalsof multiple types are transmitted through a Physical Resource Block(PRB).

In order to meet uplink signal transmission requirements of differentservices, during uplink transmission in the 5G system, a CP-OFDMwaveform and a DFT-S-FDMA waveform may be adopted. That is, duringuplink transmission in the 5G system, both of a single-carriertransmission manner and a multi-carrier manner may be supported to meettransmission requirements of different services in the 5G system onuplink transmission.

A method for transmitting an uplink signal will be introduced below incombination with FIG. 2 in detail.

FIG. 2 illustrates a schematic flowchart of a method for transmitting anuplink signal according to an embodiment of the disclosure. The methodillustrated in FIG. 2 includes the following actions.

In 210, a network device determines a physical resource for transmittingan uplink control signal in a time-domain scheduling unit.

Specifically, the time-domain scheduling unit may be an uplinkscheduling period and may be a slot. The time-domain scheduling unit mayinclude 7 OFDM symbols under the condition of a normal Cyclic Prefix(CP). The time-domain scheduling unit may include 6 OFDM symbols underthe condition of an extended CP.

The uplink control signal may include uplink signals of different types,for example, an ACK/NACK signal and a CSI feedback signal.

The physical resource may be a Resource Element (RE).

Transmission of the uplink control signal with a CP-OFDM waveform maymean that the uplink control signal is modulated through the CP-OFDMwaveform and mapped onto the corresponding physical resource.

Alternatively, as an embodiment, the physical resource for transmittingthe uplink control signal in the time-domain scheduling unit includes atleast one physical resource region, and different physical resourceregions are used to transmit uplink control signals of different types.

Specifically, the uplink control signal may include uplink controlsignals of multiple different types.

It is to be understood that the physical resource region may includemultiple RBs and the RBs may be continuous in frequency domain. Thephysical resource region may also be a physical resource region on anRB, that is, an RB may include at least one physical resource region.

Alternatively, each of the at least one physical resource regionconsists of at least one frequency-domain RB in the frequency domain.

Alternatively, the uplink control signal includes uplink control signalsof different types, the physical resource for transmitting the uplinkcontrol signal may be an RB, the RB includes the at least one physicalresource region, and different physical resource regions are used totransmit the uplink control signals of different types.

Specifically, the RB may be used as a minimum scheduling unit for uplinksignal transmission.

Each physical resource region in multiple physical resource regions mayinclude multiple REs continuous in the frequency domain and multipleOFDM symbols.

Alternatively, as an embodiment, the at least one physical resourceregion includes a first physical resource region, and a first OFDMsymbol of the first physical resource region in time domain is astarting OFDM symbol in the time-domain scheduling unit.

For example, the first OFDM symbol of the first physical resource regionin the time domain may be a first OFDM symbol, i.e., a starting OFDMsymbol, of a PRB.

Alternatively, the at least one physical resource region furtherincludes a second physical resource region, and the second physicalresource region and the first physical resource region are continuous inthe time domain.

Alternatively, the first physical resource region may be used totransmit the ACK/NACK signal, and the second physical resource region isused to transmit the CSI feedback signal.

Alternatively, the first physical resource region is further used totransmit reference signals. That is, both of the ACK/NACK signal and thereference signals may be transmitted in the first physical resourceregion. The reference signals are configured to demodulate the ACK/NACKsignal.

It is to be understood that an ACK/NACK feedback mode corresponding tothe ACK/NACK signal may include an ACK/NACK merging mode and an ACK/NACKmultiplexing mode. There are no specific limits made thereto in thedisclosure.

It is to be noted that, when an uplink control signal is transmitted inthe first physical resource region, the second physical resource regionmay be used to transmit uplink data; and when an uplink control signalis transmitted in the first physical resource region, an uplink controlsignal may also be transmitted in the second physical resource region.The uplink control signal transmitted in the first physical resourceregion and the uplink control signal transmitted in the second physicalresource region may belong to different types.

Specifically, FIG. 3 illustrates a schematic diagram of physicalresource configuration for transmitting an uplink signal according to anembodiment of the disclosure. It is to be understood that descriptionsare made in combination with FIG. 3 only with the condition that thefirst physical resource region includes physical resources of two OFDMsymbols as an example, and there are no specific limits made to thenumber of OFDM symbols in the first physical resource region in theembodiment of the disclosure. From FIG. 3 , it can be seen that thephysical resource in the time-domain scheduling unit (for example, aPRB) includes the first physical resource region and the first OFDMsymbol (i.e., a first OFDM symbol in the time domain) in the firstphysical resource region may be the starting OFDM symbol (i.e., a firstOFDM symbol in the time domain) in the time-domain scheduling unit.

Alternatively, as an embodiment, the at least one physical resourceregion includes a third physical resource region, and a last OFDM symbolof the third physical resource region in the time domain is a last OFDMsymbol in the time-domain scheduling unit.

It is to be understood that FIG. 4 illustrates a schematic diagram ofphysical resource configuration for transmitting an uplink signalaccording to another embodiment of the disclosure. Descriptions are madein combination with FIG. 4 by taking that the third physical resourceregion includes a physical resource of one OFDM symbol as an example,and there are no specific limits made to the number of OFDM symbols inthe third physical resource region in the embodiment of the disclosure.A physical resource corresponding to an OFDM symbol before a first OFDMsymbol (i.e., a starting OFDM symbol) in the third physical resourceregion may be configured for downlink transmission between the networkdevice and a base station. That is, downlink transmission and uplinktransmission is switched before the first OFDM symbol corresponding tothe third physical resource region, and uplink transmission between thenetwork device and the terminal may be started from the first OFDMsymbol corresponding to the third physical resource region. Physicalresource configuration manner may be called a short format for uplinkcontrol signal.

It is also to be understood that a time-frequency resource before thefirst OFDM symbol in the third transmission region may include atime-frequency resource for uplink transmission. That is, at least oneof a first physical resource or a second physical resource may exist onthe time-frequency resource before the first OFDM symbol of the thirdtransmission region. However, in a time-frequency resource configurationmethod, a mode for the uplink control signal transmitted in the thirdphysical resource region is not the short format for uplink controlsignal any more.

It is also to be understood that the second physical resource region andthe third physical resource region may be continuous in the time domain.That is, a next OFDM symbol of a last OFDM symbol in the second physicalresource region may be used as the first OFDM symbol in the thirdphysical resource region. An overlapped physical resource region mayalso exist between the second physical resource region and the thirdphysical resource region. There are no specific limits made thereto inthe embodiment of the disclosure.

It is to be noted that an overlapped physical resource region may existamong the first physical resource region, the second physical resourceregion and the third physical resource region, and the first physicalresource region, the second physical resource region and the thirdphysical resource region may also be continuous in the time domain.There are no limits made to a specific division manner for the physicalresource regions in the embodiment of the disclosure.

Alternatively, the uplink control signal includes multiple ACK/NACKsignals, in the third physical resource region, physical resources fortransmitting the multiple ACK/NACK signals and physical resource fortransmitting reference signals are not overlapped, and physicalresources in a resource group for transmitting the multiple ACK/NACKsignals and the physical resources for transmitting the referencesignals are staggered and continuously arranged in a same OFDM symbol.

Specifically, the resource group includes multiple physical resourceswhich are continuous in the frequency domain, for example, multiple REswhich are continuous in the frequency domain, in an OFDM symbol.

Alternatively, that the physical resources in the resource group fortransmitting the multiple ACK/NACK signals and the physical resourcesfor transmitting the reference signals are staggered and continuouslyarranged in a same OFDM symbol may mean that the resource group wherethe physical resources for transmitting the multiple ACK/NACK signalsare located and the physical resources for transmitting the referencesignals are staggered and continuously arranged in a same OFDM symbol.

Alternatively, in the third physical resource transmission region, themultiple ACK/NACK signals are repeatedly mapped, for a transmissiontimes of the multiple ACK/NACK signals, onto resource groups atdifferent positions after being extended and superposed by use ofdifferent orthogonal sequences or pseudo-orthogonal sequences with asame length respectively, and the resource groups include the physicalresources for transmitting the multiple ACK/NACK signals.

Specifically, the resource groups at different positions may mean thatthe positions corresponding to multiple resource groups correspond todifferent positions in the time-domain scheduling unit.

Alternatively, the resource groups at the different positions may becontinuous in at least one of the time domain or the frequency domain.

For example, FIG. 5 illustrates a schematic diagram of physical resourceconfiguration for transmitting an uplink signal according to anotherembodiment of the disclosure. From FIG. 5 , it can be seen that aposition of the physical resources for transmitting the referencesignals and a position of the resource group (a first resource group andsecond resource group in FIG. 5 ) used to transmit the ACK/NACK signalsare staggered and arranged in the last OFDM symbol. Continuous physicalresources in the first resource group are occupied by a first ACK/NACKsignal and a second ACK/NACK signal and, meanwhile, continuous physicalresources in the second resource group are occupied by the firstACK/NACK signal and the second ACK/NACK signal. That is, the firstACK/NACK signal and the second ACK/NACK signal are transmitted twice onthe physical resources in the time-domain scheduling unit. The firstACK/NACK signal and the second ACK/NACK signal may be extended andsuperposed by use of different orthogonal sequences or pseudo-orthogonalsequences with a same length.

Alternatively, as an embodiment, an overlapped physical resource regionexists between the second physical resource region and the thirdphysical resource region.

Specifically, a physical resource in the overlapped physical resourceregion may be configured for the uplink signal transmitted in the secondphysical resource region, or may be configured for the uplink signaltransmitted in the third physical resource region.

It is to be understood that the overlapped physical resource region maymean that part of physical resource region in the second physicalresource region and part of physical resource region in the thirdphysical resource region are overlapped, or the overlapped physicalresource region may mean that the second physical resource regionincludes the third physical resource region. There are no limits made toa specific overlapping form of the second physical resource region andthe third physical resource region in the embodiment of the disclosure.

Alternatively, the uplink signal includes the uplink control signal, thereference signal and the like.

Alternatively, as an embodiment, the uplink control signal includes afirst-type uplink control signal and a second-type uplink controlsignal. The method further includes that: in the overlapped physicalresource region, the network device configures a physical resource usedby the terminal for transmitting the first-type uplink signal; and inthe overlapped physical resource region, the network device configures aphysical resource used by the terminal for transmitting the second-typeuplink signal, a priority of the physical resource configured by thenetwork device for the first-type uplink signal being higher than apriority of the physical resource configured by the network device forthe second-type uplink signal.

Specifically, the overlapped physical resource region exists between thesecond physical resource region and the third physical resource region,the second physical resource region is used to transmit the second-typeuplink control signal and the third physical resource region is used totransmit the first-type uplink control signal. The network device mayconfigure a physical resource for transmitting the first-type uplinkcontrol signal for the terminal in the overlapped physical resourceregion at first, and then configure a physical resource for transmittingthe second-type uplink control signal for the terminal in physicalresources except the physical resource for transmitting the first-typeuplink control signal.

Alternatively, the first-type uplink control signal may include theACK/NACK signal, and the second-type uplink control signal includes theCSI feedback signal.

For example, FIG. 6 illustrates a schematic diagram of physical resourceconfiguration for transmitting an uplink signal according to anotherembodiment of the disclosure. From the schematic diagram of the uplinktransmission resource configuration in FIG. 6 , it can be seen that thefirst physical resource region includes a physical resourcecorresponding to a first OFDM symbol, the second physical resourceregion includes physical resources corresponding to a second OFDM symbolto a fifth OFDM symbol, and the third physical resource region includesphysical resources corresponding to a fourth OFDM symbol to a seventhOFDM symbol. That is, the overlapped physical resource region betweenthe second physical resource region and the third physical resourceregion includes the physical resource corresponding to the fourth OFDMsymbol and the physical resource corresponding to the fifth OFDM symbol.The first physical resource region is used to transmit the ACK/NACKsignal, the second physical resource region is used to transmit the CSIfeedback signal, and the third physical resource region is used totransmit the ACK/NACK signal.

It is to be noted that any physical resource region in the firstphysical resource region, the second physical resource region and thethird physical resource region may further be used to transmit thereference signal. Descriptions are made in combination with theschematic diagram of the resource configuration in FIG. 5 by taking thatthe reference signals are transmitted in the first physical resourceregion as an example.

Alternatively, as an embodiment, the overlapped physical resource regionexisting between the first physical resource region or the secondphysical resource region and the third physical resource region meansthat the network device configures at least one of the physicalresources for transmitting the ACK/NACK signal and/or the referencesignal in the third physical resource region for at least one of theuplink control signal and/or reference signal transmitted in the firstphysical resource region or the second physical resource region. In sucha case, the at least one of the uplink control signal or referencesignal transmitted by occupying the physical resource in the thirdphysical resource region may be punctured by the at least one of anuplink control signal or reference signal originally required to betransmitted in the third physical resource. Therefore, the problem ofresource conflict between the uplink control signal and reference signalin different physical resource regions is solved.

In 220, the network device receives the uplink control signal on thephysical resource for transmitting the uplink control signal, the uplinkcontrol signal being transmitted by use of a CP-OFDM waveform.

Alternatively, as an embodiment, the method further includes that: thenetwork device determines a physical resource used by a terminal fortransmitting a reference signal in the time-domain scheduling unit, thephysical resource for transmitting the reference signals beingconfigured in one of the at least one physical resource region.

Alternatively, the third physical resource region is further used totransmit the reference signals, and the second physical resource regionis further used to transmit the reference signals.

Specifically, the reference signals may be used to demodulate theACK/NACK signal.

Alternatively, the reference signals in the second physical resourceregion are not transmitted in the overlapped physical resource region.

It is to be noted that the positions of the physical resourcescorresponding to the physical resources for transmitting the referencesignals may be fixed. That is, the physical resources for transmittingthe reference signals in the second physical resource may be fixed andthe physical resources for transmitting the reference signals in thethird physical resource may also be fixed. Since the priority of thephysical resource configured for the uplink signal transmitted in thesecond transmission physical resource region in the overlapped physicalresource region is lower than the priority of the physical resourceconfigured for the uplink signal transmitted in the third transmissionphysical resource region, for avoiding the condition that the physicalresource originally used to transmit the reference signal is used totransmit the uplink control signal in the third physical resourceregion, and thus the network device may not demodulate the ACK/NACKsignal in the first transmission region according to the referencesignal (in such a case, the physical resources for transmitting thereference signals may not be configured in the first physical resourceregion), the physical resources for transmitting the reference signalsmay not be configured in the overlapped physical resource region whenthe physical resources are configured for the reference signalstransmitted in the second physical resource region.

For example, in the schematic diagram of the uplink transmissionresource configuration in FIG. 6 , the reference signals are nottransmitted in the overlapped physical resource region between thesecond physical resource region and the third physical resource region,i.e., on the physical resource corresponding to the fourth OFDM symboland the physical resource corresponding to the fifth OFDM symbol.

Alternatively, the physical resources for transmitting the referencesignals are distributed in the frequency domain or the time domain, orthe physical resources for transmitting the reference signals arecontinuous in the frequency domain and/or the time domain.

Specifically, in the arrangement of the physical resources fortransmitting the reference signals in the first physical resource regionillustrated in FIG. 6 , in an OFDM symbol, resource groups where thephysical resources for transmitting the reference signals are locatedare distributed in the frequency domain.

In the arrangement of the physical resources for transmitting thereference signals in the second physical resource region illustrated inFIG. 7 , the resource group where the physical resources fortransmitting the reference signals are located includes multipleresource groups, and the resource groups where the physical resourcesfor transmitting the reference signals are located are distributed inthe frequency domain (which may mean that multiple resource groupscorrespond to different frequencies). Each resource group used totransmit the reference signals occupies two continuous OFDM symbols.

In an arrangement of the physical resources for transmitting thereference signals in the second physical resource region illustrated inFIG. 8 , the resource group where the physical resource for transmittingthe reference signals are located includes multiple resource groups,each resource group in the multiple resource groups occupies twodifferent OFDM symbols and, in one OFDM symbol, the resource group wherethe physical resource for transmitting the reference signals is locatedis distributed in the frequency domain.

It is to be noted that descriptions are made in the embodiment of thedisclosure by taking that the resource group used to transmit thereference signal includes two physical resources as an example. Theresource group used to transmit the reference signal may also includefour physical resources. There are no specific limits made to the numberof physical resources in the resource group for transmitting thereference signal in the embodiment of the disclosure.

Alternatively, as an embodiment, the uplink control signal includes themultiple ACK/NACK signals, in the first physical resource region,physical resources for transmitting the multiple ACK/NACK signals andphysical resources for transmitting a reference signal are notoverlapped, and physical resources in a resource group for transmittingthe multiple ACK/NACK signals and the physical resources fortransmitting the reference signals are staggered and continuouslyarranged in a same OFDM symbol.

Specifically, the resource group may include a group of physicalresources which are continuous in the frequency domain. That is,multiple resource groups may be included in an OFDM symbol.

Alternatively, that the physical resources in the resource group fortransmitting the multiple ACK/NACK signals and the physical resourcesfor transmitting the reference signals are staggered and continuouslyarranged in a same OFDM symbol, which may mean that the resource groupwhere the physical resources for transmitting the multiple ACK/NACKsignals are located and the physical resources for transmitting thereference signals are staggered and continuously arranged in a same OFDMsymbol.

The resource group where at least part of physical resourcestransmitting the multiple ACK/NACK signals are located may mean that allof the physical resources for transmitting the multiple ACK/NACK signalsare located in a resource group. The resource group where at least partof the physical resources for transmitting the multiple ACK/NACK signalsis located may also mean that part of the physical resources fortransmitting the multiple ACK/NACK signals are in a resource group andthe other part of the physical resources for transmitting the multipleACK/NACK signals are in other resource group(s).

Alternatively, when the physical resources for transmitting the multiple

ACK/NACK signal are in multiple resource groups, the multiple resourcegroups are continuous or distributed in the frequency domain.

For example, FIG. 9 illustrates a schematic diagram of physical resourceconfiguration for transmitting an uplink signal according to anotherembodiment of the disclosure. In a resource configuration mannerillustrated in FIG. 9 , after the ACK/NACK signals are extended, eightphysical resources (for example, REs) are required to be occupied totransmit the ACK/NACK signals. However, since there are only fourphysical resources in a resource group between two physical resourcesused to transmit the reference signals, two resource groups, totallyeight physical resources, may be configured for the extended ACK/NACKsignals, the two resource groups are discontinuous in the frequencydomain but the physical resources in each resource group are continuousin the frequency domain.

It is to be understood that the extended ACK/NACK signals aretransmitted by the physical resources in the resource groups.

Alternatively, physical resources in the resource group where thephysical resources for the multiple ACK/NACK signals are located arecontinuous in the frequency domain.

Alternatively, as an embodiment, the multiple ACK/NACK signals aresuperposed and mapped onto the resource group after being extended byuse of different orthogonal sequences or pseudo-orthogonal sequenceswith a same length respectively.

For example, after ACK/NACK signals of a first group are extendedthrough a first orthogonal sequence and ACK/NACK signals of a secondgroup are extended through a second orthogonal sequence, the ACK/NACKsignals of the first group and the ACK/NACK signals of the second groupmay have a same length. For example, four REs may be occupied by theACK/NACK signals of the first group and the ACK/NACK signals of thesecond group, the ACK/NACK signals of the first group and the ACK/NACKsignals of the second group may be mapped onto the same resource group,and the resource group may include four REs.

Alternatively, as an embodiment, the uplink control signal furtherincludes the CSI feedback signal, the physical resource for transmittingthe CSI feedback signal and physical resources for transmitting thereference signals in the second physical resource transmission regionare not overlapped, and the physical resources in the resource group fortransmitting the reference signals are continuous in the time domain.

For example, the resource group for transmitting the reference signalsincludes two REs, i.e., a first RE and a second RE. The first RE may bean occupied RE in the first OFDM symbol and the second RE may be anoccupied RE in the second OFDM symbol. The first OFDM symbol and thesecond OFDM symbol are continuous in the time domain, and the first REand the second RE correspond to a same subcarrier.

Alternatively, as an embodiment, in the first physical resourcetransmission region, the multiple ACK/NACK signals are repeatedlymapped, for a transmission times of the multiple ACK/NACK signals, ontoresource groups at different positions after being extended andsuperposed by use of different orthogonal or pseudo-orthogonal sequenceswith a same length respectively.

Specifically, the resource group includes the physical resources fortransmitting the multiple ACK/NACK signals.

For example, after the ACK/NACK signals of the first group are extendedthrough the first orthogonal sequence and the ACK/NACK signals of thesecond group are extended through the second orthogonal sequence, theACK/NACK signals of the first group and the ACK/NACK signals of thesecond group may have a same length. For example, four REs may beoccupied by the ACK/NACK signals of the first group and the ACK/NACKsignals of the second group, the ACK/NACK signals of the first group andthe ACK/NACK signals of the second group may be mapped onto differentresource groups respectively, and each resource group may include fourREs.

Alternatively, as an embodiment, the multiple ACK/NACK signalscorrespond to downlink data blocks in different time-domain schedulingunits respectively, or the multiple ACK/NACK signals correspond todifferent codewords of a same downlink data block.

The uplink signal transmission method will be described in combinationwith FIG. 10 with a subframe as an example. FIG. 9 illustrates aschematic diagram of a method for transmitting an uplink signalaccording to another embodiment of the disclosure. From the uplinktransmission method illustrated in FIG. 10 , it can be seen that anuplink subframe contains ACK/NACK signals of a subframe #0, subframe #1and subframe #k for downlink transmission. The ACK/NACK signals of thesubframe #0 and the subframe #1 are mapped onto physical resources in afirst resource group of the uplink subframe. After the physicalresources in the first resource group are occupied by the ACK/NACKsignals, the ACK/NACK signals of the subframe #k may be mapped onto aphysical resource in a second resource group corresponding to a subframefor uplink transmission.

Alternatively, as an embodiment, before the operation that the networkdevice receives the uplink control signal on the physical resource fortransmitting the uplink control signal, the method further includesthat: the network device transmits indication information to theterminal, the indication information being used to indicate the physicalresource for transmitting the uplink control signal in the time-domainscheduling unit.

Alternatively, as an embodiment, the method further includes that: thenetwork device determines a transmission times needed for transmissionof the uplink control signal and/or a length of an extended sequence ofthe uplink control signal; and the network device indicates thetransmission times needed for transmission of the uplink control signaland/or the length of the extended sequence of the uplink control signalto the terminal.

Specifically, the transmission times may be a repeat count needed foruplink control signal transmission by the terminal.

Alternatively, the operation that the network device indicates thetransmission times needed for transmission of the uplink control signaland/or the length of the extended sequence of the uplink control signalto the terminal includes that: the network device transmits DCI to theterminal, the DCI carrying the transmission times needed fortransmission of the uplink control signal and/or the length of theextended sequence of the uplink control signal.

Alternatively, the operation that the network device indicates thetransmission times needed for transmission of the uplink control signaland/or the length of the extended sequence of the uplink control signalto the terminal includes that: the network device transmits a length ofa sequence of the uplink control signal to the terminal; and the networkdevice transmits a number of the physical resource for transmitting theuplink control signal to the terminal.

Specifically, the network device indicates the sequence length fortransmitting of the uplink control signal and the number of the physicalresource for transmitting the uplink control signal by the terminal tothe terminal, which may enable the terminal to determine thetransmission times (which may be a repeat count) for transmitting theuplink control signal according to the sequence length for transmittingthe uplink control signal and the number of the physical resource fortransmitting the uplink control signal by the terminal.

For example, if the terminal determines that the sequence length fortransmitting the uplink control signal is 4 and the network deviceconfigures 8 REs for the terminal to transmit the uplink control signal,the terminal may determine that the transmission times for transmittingthe uplink control signal is 2.

Alternatively, the operation that the network device indicates the atleast one of the transmission times needed for transmission of theuplink control signal or the length of the extended sequence of theuplink control signal to the terminal includes that: the network devicetransmits high-layer signaling to the terminal, the high-layer signalingcarrying at least one of a transmission times needed for transmission ofa first-type uplink signal or a length of an extended sequence of thefirst-type uplink signal.

FIG. 11 illustrates a schematic flowchart of a method for transmittingan uplink signal according to another embodiment of the disclosure. Themethod illustrated in FIG. 11 corresponds to the method illustrated inFIG. 2 . For simplicity, specific details will not be elaborated herein.The method illustrated in FIG. 11 includes the following actions.

In 1120, the terminal transmits the uplink control signal to a networkdevice on the physical resource for transmitting the uplink controlsignal, the uplink control signal being transmitted by use of a CP-OFDMwaveform.
